board. Carefully tuck any excess wire or ribbon cable down
into the module (so neither will be in the way when you
reinstall the module).
Reinstalling Modules
Reinstall the modules one at a time. To help make alignment
easier, install the first processor module in the left-most
position, the second module in the center position, and the
third module in the right-most position.
Hold the module by its handle, supporting it from underneath
if necessary. Align the two printed circuit boards on the
processor module with the alignment guides at the top and
bottom of the controller chassis.
Open the two module release levers by pulling them toward
you.
Carefully slide the module into the chassis. Be careful to keep
the module aligned while sliding it straight into the chassis.
The module should mount into the chassis with a minimum of
resistance. If the module does not mount easily, do not force
it. Remove it and check it for bent or damaged pins. If the
pins look okay, try reinstalling the module.
When the module is almost fully into the chassis, the release
levers will contact the chassis and begin to rotate closed.
Press the levers closed to seat the module in the chassis.
If the module does not seem to have seated correctly, open the
release levers and gently pull it back off the seat and out of
the chassis. Check for bent or damaged pins. If any pins are
bent or damaged do not install the module. Do not try to
straighten bent pins. Instead return the module to ICS for
repair or replacement. If the pins look okay, try reinstalling
the module. You may need to remove the board assembly and
realign the CPU boards in the assembly. See the tip, above.
After the module is properly seated, tighten the retaining
screw at the top of the module.
